NOTE:
This option applies only to voice-dial calls, and is only valid when the
Automatic Speakerphone Activation
option (see below) is set to
Yes
.
Automatic Speakerphone Activation
This option is set, by default, for
Yes
, permitting automatic activation of the
speakerphone when you use your terminal to dial a voice call.
Setting this option to
No
causes the 8400B Plus Data Module to disable the
automatic speakerphone feature, and necessitate the use of a handset or
manual speakerphone activation.
This option has no effect if the voice terminal does not have a speakerphone.
When
Immediate Speakerphone Activation
and
Automatic Speakerphone
Activation
are set to
Yes
, the 8400B Plus Data Module automatically activates
the speakerphone at the beginning of the voice call so you can hear dial-tone
and touch-tones.
NOTE:
To enable this feature, the Telephone Provides Dialing option must also be
set to
Yes
.
When
Immediate Speakerphone Activation
is set to
No
and
Automatic
Speakerphone Activation
is set to
Yes
, the activation of the speakerphone is
delayed until dialing is complete.
